Musnad Ahmad 1258:0

Narrated to us by Yahya ibn Sa’id, from Sufyan, who said: Narrated to us Habib ibn Abi Amrah, from ‘Aishah bint Talhah, from Umm Malik al-Bahziyyah, that she came to the Messenger of Allah (ﷺ) and mentioned to him the charity of the wealthy and the poor. She said: "O Messenger of Allah, I do not have anything except what my husband, Abu Malik, brings to me." The Messenger of Allah (ﷺ) said to her: "O Umm Malik, do not withhold, lest it be withheld from you."
